Order purpose statement

Although there are no known confined spaces (CS) managed by Aviation Safety (AVS), AVS employees may be in close proximity to CS or permit-required confined spaces (PRCS) at non-Federal Aviation Administration (FAA) owned or controlled locations. These locations are external industry workplaces including aircraft accident sites visited by AVS personnel in the performance of their work-related roles and responsibilities. The purpose of this order is to provide requirements and guidelines to protect AVS personnel from injury, illness, or death while performing work-related duties near work areas identified as CS or PRCS. This order applies to all AVS personnel who work at external industry workplaces and aircraft accident sites. External industry workplaces include facilities where aircraft or aircraft components manufacturing, maintenance, overhaul, or aircraft accident forensic reconstruction occurs or other work-related locations visited by AVS personnel. The definition of external industry workplaces in Appendix A has additional examples. This order specifies the actions necessary to protect the health and safety of all AVS employees, and provides the requirements for development, implementation, and maintenance of a CS entry program. Appendix A contains the definitions and further explanation of associated CS terminologies used throughout this order. Appendix B is the AVS summary of types of CS.
